`To all whom z' mit@ concern:

Be it known'th'at we, CHARLEs Crrnrsrol 'rHER ROBERTS and JOHN EDWARD BARGHEL, both citizens of.the United States, both re` pensions f-orl Radiator-Cores; and v,we do` hereby declare the following to -l be a full, clear, and exact description of thevinvention, such as will enable others skilled in theart to which it appertains to makeand use the same.

This invention relates to a suspension for radiator cores especially adapted for automobiles and other vehicles,` and has for one of its objects to provide a means of this nature which'will avoid, to a large extent, the injurious racking strains that are transmitted to radiator cores by the suspensions heretofore proposed.

With this andA other objects in view the invention consists in the novel details of con- Y struction and combination of parts more fully hereinafter disclosed and particularly pointed out in theclanns. N

Referring to the accompanying drawin sv forming a partof this specification in whic i like numerals'designate like parts in all the viewszv Figure 1 is an elevational view of an auto mobile radiatorcore detached from its suspension;

Fig. 2 is a diagrammatic view of an automobile radiator core surrounded by its suspension ready for attachmentto ,the ve- Fig. 3 is .an enlarged partially sectional detail view of a portion of an automobile radiator core showing the construction of the parts and also one of the out away corners of said core; 1

Fig. `4 is a y proved suspension detached from the core; and v v Fig. 5 isa view showing the well known form 4of suspension now in use.

1 indicates one form of automobile ra'- diator core suited to this invention and having the air cells 2, the water passages 8, the division plate 4 between contiguous rows of cells 2, and the plaits or'other` cell partitions 5 separatin the individual cells and reaching to the division plate4.

perspective view of the As is well known, in this type of radiator core the edges of the strips 9 from which the plaits 5 are formed are ofset as at G and 47, to form water passages such as 3 between them. Y

The meeting surfaces 8 between the offsets 6 and 7 are soldered in place, thus forming seams; but even when the work is most carefully done, with the form of suspension heretofore employed, sudden racking strains engendered by the passa e of the vehicle over rough roads, ifof su cient magnitude, are

"liable to open said surfaces orseams 8 in spots, and thuslgive rise to leaks.

' Further the individual cell strips 9 as well as the division strips 4 are of necessity made from thin sheet metal. Accordingly, with the old style'of suspension,they can be bent or displaced to a greater or less extent, under the influence of suiiiciently heavy or sudden shocks or strains, that are encountered in the passage over rough roads. lt follows that their meeting edges or lines of contact located between contiguous water passagespbeing soldered together, as at 13, are in such Cases liable to become separated, and thus 'stillfurther injure the efficient operation of theadiator.

In order to 'secure the bottom tank 14 to the radiator core 1, it is customary to cut off the corners" 15 and 16'of said core and tb solder said tank 14 to said cut away corners as well as to the uncut portion 11 of said core 1, thus making said tank substantially rigid with said core along the brokensline 12 all as will be clear from Figs. 2 and 5. ln the same way the top corners 17 and 1S of said core lare usually cutaway and the top tank 19 soldered thei'feto and to the uncut portion 20 of said core 4along the broken line 21.

In the suspensions employed prior to this invention, the side reinforcing pieces 25 from the steel frame-work 29 of the autornob bile i to the brackets 27 through said brackets to the reinforcing pieces 25, through said reinforcing pieces to the solder 2 6, through said solder to the tanks such as 14 and 19 and to the solder 22,`it is clear thatbending or racking strains due to rough- -nesses of the road will be transmitted from the said tanks along the broken lines 12 and 21 to the core 1'..

- other than along a straight line, tend to put very complicated andA severe racking strains l on the entire interior' `construction of the core 1, thus greatly promoting the chance of developing leaks in use.

According to 'the invention no w to be dis.- closed, however, the above obj ections are either entirely done away with or are greatly v decreased. That is to say, instead of causing the racking and bending-strains to be transmitted directly from the frankie-work 29 to localized portions of the core suchas those occupied bythe solder 22, these'said strains are distributed evenly all around the core by means of a hoop under tension which is not at any point rigidly attachedoto lsaid core. In other words, according to the pres- `ent invention, a hoop 40 having the side i 43 and 44, is provided with tensioning mem-- members 41 and 42, land the end members v bers, and said hoop 40 therefore encircles frame 29 of the automobile as heretofore, i

under tension the tanks 14 and 19 as well as the core 1 without being rigidly 'attached to said tanks or core at any single point, all as will'be clear from` Fig. 2. Saidhoop 40 is provided with 4the suspension brackets 27 which are conveniently attached to the steel i and the members 41 and 44 are provided with the tensioning ears 45 and 46 respectively, through which adjusting bolts such as 47 may be passed, in order to adjust the tension of said hoop, all -as will be clear from'Fig. 2. No .solder suchas 26 or other rigid fastenings are had between the said hoop 40 and the tanks, or between the said hoop 40 and the core, and it therefore 'fol'- lows that when sudden strainsor jolts are imparted to the said brackets 27 or to the said tensioned hoop the said strains or jolts are transmitted to the said hoop around the entire structure whether the' supporting members 27 are provided or not so that the tan-ks as well as the body portion of the core 1 are more evenly strained than heretofore,

and thus local straining 'is avoided.` Especially is'this the case when one bracket 27A is more suddenly raised or 'lowered than is the otherLfor in such cases under the'old practice, the-local straining was often' very?` severe.v Under' this invention, on the other hand, such strains are taken circumferentially of the hoop under tension and' itis possible for thestrains to be distributed substantially all around the core even if no rigid connection with the framesuch as 27 exist.'

The brackets 50 aid in secu-ring the outer work while the anges 51 aid the hoop in holding thel core andta'nks in place.

When desired 'cushioning members 52 of cork, rubber, leather, etc., maybe employed at the corners of the hoop as indicated in dotted lines Fig. 4, but lordinarily such members need not be used.

What is claimed is:--

1. In an apparatusofthe class described the combination, of ajcellular radiator core .casing not shown, tothe hoop and framesoV for automobiles; a tank associated'with said.

core; and a hoop under tension surrounding said core and tank, substantially as 'described.
